The main symptoms of vaginitis are vulvar itching and abnormal vaginal discharge, but the symptoms may vary depending on the type of vaginitis. Trichomonas vaginitis Causative agent: Trichomonas vaginalis, a common form of vaginitis. Mode of transmission: direct sexual intercourse, can also be indirectly transmitted.

Bacterial vaginitis Characteristics: This is a mixed infection caused by the imbalance of normal flora in the vagina. The normal vagina is dominated by Lactobacillus, which produces hydrogen peroxide. When suffering from bacterial vaginosis, there is a decrease in the number of Lactobacillus that can produce hydrogen peroxide in the vagina, leading to the proliferation of other microorganisms, mainly Gardnerella, anaerobic bacteria, and Mycoplasma hominis. Clinical manifestations: mild pruritus vulvae, thin homogeneous discharge with a fishy odor. Laboratory examination clues: positive cells; positive ammonia odor test; vaginal pH>4.5 to confirm the diagnosis. PREVENTIVE MEASURES: Change incorrect lifestyle. Do not perform vaginal douching unless advised by a doctor. 2. Both men and women should pay attention to sexual hygiene. Age-related vaginitis Characteristics: Due to the low level of estrogen in postmenopausal women, the vaginal wall atrophies, the mucous membrane thins, and the local resistance is low, which makes it easy for pathogenic bacteria to invade the vagina and cause inflammation. Clinical manifestations: leukorrhea, vulvar itching, burning sensation, examination can be seen vaginal atrophy, epithelial folds disappeared, pitting congestion. Sometimes superficial ulcers are seen. According to the history of menopause, ovarian surgery, pelvic radiology history, the diagnosis is not difficult. Preventive measures: 1.

During the period of illness, women should change and wash their underwear daily, and the underwear should be loose and comfortable, and made of pure cotton fabrics. 4. Wash the vulva with warm water. Non-specific vaginitis Characteristics: Because the vulva is close to the urethra and anus, it is often stimulated by menstrual blood, vaginal secretions, urine and feces, and if no attention is paid to skin cleansing, it is easy to cause vulvovaginitis and vaginitis. Clinical manifestations: vulvar skin mucosa itching, pain, burning pain, check the skin congestion, swelling, vesicles, often with scratches, severe cases form ulcers or herpes.
